Similar letters of reference in the several figures indicate the same parts.

The accumulator consists of a plate A, of any suitable metal of good heat conducting property, such as iron, and is of any desired shape to suit the cooker, that illustrated. being shown as circular.

surface of the plate A is formed a series of upwardly extending concentric flanges or ribs B, suitably spaced apart to form mter- .mediate grooves or channels C, as shown clearly in the drawings. The two outermost grooves or channels C extend unbroken completely around the plate, while the remaining channels are preferably provided with elongated slots 0, as shown clearly in Fig. 1,

The two outermost channels extending unbrokenl throughout their length, when the receptac sis in place there on, the heat will be packed or retained these channels and will be distributed uniforml'y around the bottom ofthe receptacle so that the food stuif will be heated ,evenly.

By having the accumulator. raised from the bottom'of the cooker by means of the lugs (Z, a space is left below the accumulator whereby a complete circulation .is secured central solid portion of the plate-will act as,

a spreader slots.
